NIST SP 800-53 Rev 5 covers 53.3% of APPI
16 of the 30 controls in APPI are already satisfied by evidence you collected for NIST SP 800-53 Rev 5. 14 are genuine gaps. Every claim below was judged against both control sets and then argued against; the ones that did not survive are published further down with the reason each failed.
This number is directional. It says how much of APPI your NIST SP 800-53 Rev 5 evidence satisfies. The reverse pair is a different number, often very different, because a security standard has enormous depth for access control and almost none for lawful basis or data subject rights.
35 candidate mappings were examined and 0 were removed. Signed off 2026-08-19, review level machine verified. Mappings were judged by Claude Code rather than read line by line by a practitioner. Every claim shows its reasoning so you can check it. Ask and a practitioner will review this pair.
Where the gaps are
Coverage is never evenly spread. A source standard usually satisfies one part of a target almost completely and barely touches another, and which part is which is the thing worth knowing before you plan the work.
Theme level, not control level, deliberately. The per-control list of what is evidenced and what is a gap is the report itself, so publishing it here would be publishing the thing being sold.
Claims that held
A sample. Each one names the control whose evidence does the work, the control it satisfies, and why.
Identifying and documenting the purposes for processing personal information matches purpose specification.
Processing must be restricted to the documented purposes, which is the handling restriction.
Processing is restricted to what the documented authority permits, requiring consent otherwise.
Applying defined controls to specific categories of personal information is the special care requirement.
Notice to individuals about the processing of their information, clear and available, matches directly.
Organization-wide policies for reviewing accuracy and deleting inaccurate information match.
Checking accuracy, relevance, timeliness and completeness, and correcting or deleting, matches directly.
Information must be retained per policy and disposed of when the purpose no longer requires it.
Claims that did not hold
Nothing proposed for this pair was rejected in review. That is unusual and worth knowing rather than hiding: it means the candidate set was small and every candidate held.
The full report
Everything above is a sample. The report is every evidenced control and every gap, with the reasoning and the source document behind each one, in a form you can hand to an assessor. $299, emailed immediately.
